I really feel you on this -- choosing the right OB and hospital is such a big decision and the costs can feel so overwhelming when you are trying to plan ahead. I don't have the exact figures for Dr Edwin Thia specifically, so I would not want to give you a number that turns out to be wrong lah. Your best bet is to call his clinic directly to ask for a fee estimate, and also check with Mt E on their delivery package breakdown so you can compare against your insurance or Medisave coverage.
